The supermarket chain analyzed consumer behaviour across 465 stores internationally, and said that purple foods are picking up momentum. “Back to the Roots Purple Corn Cereal, Jackson’s Honest Purple Heirloom Potato Chips, Que Pasa Purple Corn Tortilla Chips, Love Beets and Stokes Purple Sweet Potatoes are all examples of this fast-growing trend,” they said in an online statement.

Acai bowls, which have been bouncing around the Internet for the past couple of years, are in step with the projected trend. The tropical, grape-like berries “contain antioxidants, fibre and heart-healthy fats,” according to the Mayo Clinic. The natural vibrant colour of purple foods in general is often a indicator of antioxidant value, Whole Foods said in its statement.

Agreeing that purple foods are the bearers of natural nutritional benefits, Matthew Plowman, a Nutrition Adviser at Cardiff Sports Nutrition told the Telegraph: “The benefits of antioxidants have long been discussed, but they are known to fight disease, keep you looking younger, reduce inflammation and are good for your heart – basically, why wouldn’t you eat them?”

Along with purple foods, Whole Foods predicts a 2017 boost in wellness tonics such as drinking vinegars and turmeric elixirs, products from byproducts such as probiotic drinks made from the whey leftover from yogurt-making, more diverse Japanese ingredients and condiments, and “coconut everything.”
